Gasoline is a liquid. It is a liquid because the gasoline u pour
Whether or not the density changes if some of the liquid evaporates between the time the liquid is delivered to the beaker and the time it is measured depends on the liquid. For almost all liquids, the answer is no because there was not enough time. Water will have a density of approximately 1 and if a small amount evaporates, it will still have the same density. If you had the beaker at 100C and the room at 0C and waited until the water was 4C, it would make a difference. If the water was at 40C and the room was at 30C, it would almost make no difference. A very few substances would undergo tremendous cooling. That would bring a corresponding increase in density.
Patrol (also known as petroleum ether) evaporates at room temperature because it has a low boiling point. The molecules in patrol have weak intermolecular forces, which allows them to easily escape from the liquid phase and enter the gas phase at room temperature. This rapid evaporation is why patrol is highly volatile and can be dangerous if not handled properly.
As you use the tank, the pressure inside goes down. As the pressure drops, the temperature also drops because of something called the Ideal Gas Law (see the "Ideal Gas Law" Related Questions linked the left of this answer). Ice forms on the tank because water moisture in the atmosphere is condensed on the cold tank and then frozen.
no
The difference at room temperature is not significant.
When the liquid is exposed to extreme heats, it evaporates, forming a gas. This is because of the particles shrinking and being able to move around more freely. If it is exposed to cold temperatures, the particles enlarge, so that there is not much room for movement, causing a solid object.
Liquid nitrogen evaporates instantly at room temperature. Nitrogen cannot be a solid at any temperature greater than -346.00 °F (-210.00 °C,).
Clearly, this depends on the temperature of the room. In most countries, cooking oil will be liquid at room temperature. However in very cold countries, cooking oil will be solid at room temperature.
Anything at room temperature is regarded neither cold nor hot. <><><><><> If the question meant "Is nitrogen solid, liquid, or gaseous at room temperature?", then the answer is gaseous.
It takes about two hours.

Methanol has a melting point of -97° C, or -143° F, and a boiling point of 65° C, or 148° F. With room temperature at 20° C (68° F), methanol is a liquid. However, with it's relatively low boiling, it evaporates quickly at room temperature.

Evaporative cooling. As the water evaporates from your body it takes with it a good deal of energy (heat) as the latent heat of vaporisation
We feel cold when a drop of petrol falls on our skin because, heat from our body is transferred to petrol which usually evaporates at normal room temperature when it is exposed.
